Concept kits have become very popular over the past few years, with many fans creating or at least sharing them as they voice their disappointment about the actual strips released by the likes of Adidas, Nike and Puma.

The main downside of concepts, obviously, is that they are not usually available to buy - now, Airo Sportswear are aiming to change this. Originally a company focused on custom kits for different sports including football, Airo have lots of unique and interesting designs in stock, amongst them 32 kits for all teams in the World Cup. The jerseys retail at GBP 35, which is another plus about them in our books.
